           Summary: Wrong code for avx512ne2ps2bf16_maskz intrinsics since
                    gcc13
           Product: gcc
           Version: 13.1.0
            Status: UNCONFIRMED

cat test.c

#include <immintrin.h>

__m512bh cvttest(__mmask32 k, __m512 a, __m512 b)
{                                                
      return _mm512_maskz_cvtne2ps_pbh (k,a,b);  
}

gcc -O2 -mavx512bf16

        kmovd   %edi, %k1
        vcvtne2ps2bf16  %zmm0, %zmm1, %zmm0{%k1}{z}
        ret

The code is wrong compared to clang, the input operand order was inverted.
